Evo E-Tec OS Stem

The Evo E-Tec OS Stem is designed for a standard 1-1/8-inch (28.6mm) threadless steerer tube and requires handlebars with a 31.8mm clamping diameter. Please verify these measurements on your current bike before purchasing.

A 17-degree rise allows you to adjust your handlebar height to achieve a more upright or aggressive riding position. Depending on how you flip the stem, it can either raise your bars for better comfort or lower them for a more aerodynamic, performance-oriented stance.

Yes, the 3D forged alloy construction and heat-treated hardware make this stem durable enough for various disciplines, including commuting and mountain biking. Its lightweight design ensures it won't add unnecessary bulk to your setup.

The 100mm version of this stem weighs approximately 152 grams. While the weight may vary slightly depending on the specific length you choose, it is engineered to be a lightweight component that won't weigh down your front end.

A 70mm length is often considered a 'sweet spot' for many riders, offering a balance between responsive steering and a comfortable reach. Shorter stems generally provide quicker, more agile handling, while longer stems offer more stability and a stretched-out position.
